Novel Nanowire Field-Effect Transistor Biosensor With Superb Sensitivity
University of California System: University of California, Los Angeles - UCLA
posted on 02/24/2012
There has been an increasing demand for highly sensitive bio- and chemical sensor devices. Optical and MEMS methods provide highly specific platforms; however, problems of scalability and cost have hindered their employability in real field applications. With the recent advancements in nanotechnology, integrated systems have been developed through the use of silicon nw-FETs. However, the low level of output signal in the design of these sensors limit their potential applications.
Suggested Uses
Chemical/Biomedical sensors
- Toxin detection, Disease diagnosis, Drug screening, Label-free biosensing (proteins, DNA, enzymes), Environmental monitoring
Advantages
- Standard semiconductor processing methods
- Tunable electronic properties
Detailed Description
Researchers at UCLA have developed a novel, highly-sensitive integrated biochemical sensor with significant detection performance. Through integrating a sensing nanowire with a nw-FET channel, a built-in signal amplification mechanism is introduced, which greatly enhances detection sensitivity. Additionally, because the technology is compatible with conventional silicon fabrication techniques, it provides a simple and low-cost solution to integrated biomedical and chemical sensors.
